The objective of the present work is to provide a stochastic approach for the prediction of the probability of the successful separation of a sample with a known number of components using a chromatographic system wit...
As a reminder from the literature, high-performance liquid chromatography (HPLC) testing allows for the separation and accurate measuring of the various hop acids in dry hopped beers. In other words, HPLC testing allows for measuring the individual hop acids: iso-alpha-acids, alpha-acids, humulin...
It concludes that the retention mechanism of polymers on RPLC can be explained by conventional, partition/adsorption chromatography theory. Linear Van't Hoff plots are obtained from isocratic, isothermal retention data of polystyrenes and poly(ethylene oxide)'s. Thermal gradients over the separation ...
Chromatography, High Pressure LiquidHydrogen-Ion ConcentrationSolventsStructure-Activity RelationshipTechnetiumThe uptake of some ionogenic radiopharmaceuticals may be explained on the basis of a pH shift theory. An HPLC method for p K a measurement has been developed for radiotracers. It has been tested...
based on the analysis of high performance liquid chromatography (HPLC) fingerprint, combined with the quantitative analysis of multi-components by single marker (QAMS) method. The contents of the seven components, including gastrodin,p-hydroxybenzyl alcohol,p-hydroxy benzaldehyde, parishin A, parishin ...
Here, we present the optimization and screening qualitative validation of two multianalyte methods in bovine muscle tissues by ultra-high-performance liquid chromatography coupled to high-resolution mass spectrometry with an Orbitrap-type analyzer, operated with a heated ionization source in positive and ...
